BDO (1,4-Butanediol)


BDO (1,4-Butanediol) Nature:

Colorless oily liquid, flammable, miscible with water. Soluble in methanol, ethanol, acetone, slightly soluble in ether. Boiling point 228 ℃. Melting point 20.2 ℃. Flash point (open cup) 121 ℃. Relative density 1.0171. Refractive index 1.4461.

BDO Purpose:

BDO is mainly used to manufacture tetrahydrofuran, y-butyrolactone, polyurethane and thermoplastic engineering plastic PBT resin. BDO can also be used to prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives. 1,4-Butanediol is also used to prepare vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, humidifiers, softeners, adhesives and brighteners in electroplating industry.


BDO Safety:

Poisonous. When attached to diseased or wounded skin or consumed, 1,4-Butanediol initially exhibits anesthesia, causing specific pathological changes in the liver and kidneys, and then sudden death (without prolonged latency) due to central nervous system paralysis. Oral LD50 of rats is 210~420mg/kg. Production equipment should be sealed to prevent leakage, and operators should wear protective equipment. People with wounded skin are strictly prohibited from contacting this product.Packed in aluminum, stainless steel, galvanized iron drums or plastic drums, or stored and transported in tankers according to the regulations for flammable and toxic substances. Because the melting point is as high as 20 ℃, the tank car should be equipped with a heating tube.

Storage method:

Store in a cool and ventilated warehouse away from kindling. Keep containers sealed and stored away from oxidants and water sources. Leakage emergency treatment equipment and appropriate storage materials shall be prepared. It can be stored in sealed containers made of mild steel, aluminum or copper.
BDO shall be packed in aluminum, stainless steel, galvanized iron bucket or plastic bucket, or stored and transported in tank car according to the provisions of flammable and toxic substances. Since the melting point is as high as 20 ℃, the tank car shall be equipped with heating pipe.
